Science

Mechanism of Action

This ingredient functions primarily as a humectant and moisturizer, effectively attracting and retaining water within the skin's stratum corneum to bolster hydration. It provides free amino acids, which are crucial building blocks for dermal proteins like collagen and elastin. Furthermore, its collagen oligopeptides may serve as ligands, potentially signaling fibroblasts to stimulate the endogenous production of new collagen, elastin, and hyaluronic acid. The 'TEA' (Triethanolamine) neutralization and 'isostearoyl' modification enhance its water solubility and foaming characteristics, imparting mild surfactant properties and aiding in mitigating the harshness of other cleansing agents in formulations.

Key findings

  1. 01 Topical application of hydrolyzed collagen, the base ingredient, demonstrates significant moisturizing properties at the stratum corneum, effectively reducing signs of skin aging such as dryness, laxity, and wrinkles. It contributes to visibly smoother, softer skin and improved textural qualities.
  2. 02 General usage concentrations for hydrolyzed collagen in skincare and haircare formulations typically range from 0.2% to 2.0%.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has thoroughly reviewed and concluded that Hydrolyzed Collagen is safe for cosmetic use, a finding reaffirmed in multiple reviews. While no specific maximum concentration is set for TEA-ISOSTEAROYL HYDROLYZED COLLAGEN, general hydrolyzed collagen is deemed safe without specific restrictions. The CIR is currently re-evaluating related 'Cocoyl Hydrolyzed Collagen Ingredients' for sensitization and photosensitization; however, studies on TEA-Cocoyl Hydrolyzed Collagen showed it to be nonirritating to mildly irritating on rabbit skin (10-50% concentration) and nonirritating to practically nonirritating on human skin (2-100% concentration). A single instance of photosensitization was observed in one out of 28 subjects when testing related ingredients (PCHAP and TEA-CHAP).
